It's not a stupid post. That person should have been a little less harsh with you. I personally think your art is really good. I wouldn't say it if I didn't mean it. I don't say anything just to be nice, I'd rather just not say anything at all. I mean, if you directly ask me, I'll be honest. But, anyway, maybe just look around some of the negativity in his post and take the advice about the tutorial or whatever. There's some advice in there, it's just covered in nasty. I know what it's like to be passionate about something and have someone crap on you. It's no fun. It's natural to be bummed about it, but, just keep trucking. As long as you enjoy your art, the process and the result, that's all that really matters.
